Threat Intelligence sharing practices for Security Operation Centres March 19 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Motivation • The future of academic computing security – Romain, CHEP 2016 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Motivation • Adversaries are motivated and well funded – Cybercrime – Better funded than us • Malware as a Service (Maa. S) – Ransomware – Straightforward to spend a few dollars for a Do. S • What do we have? – Our community 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Motivation • Within a given community (such as the WLCG), we see similar threats from similar actors • Acting together, we can establish common response mechanisms and support each other • By sharing threat intelligence we can better inform fellow sites to take action – Active (firewall blocks) – Passive (awareness and improved response) 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Motivation • Grid and campus teams • Traditionally, haven’t always worked together • Additional benefit of threat intelligence – Provide route to increase cooperation – Grid team has intelligence – Campus team has access to deeper (network) monitoring 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Introduction • Key element: sharing between trusted parties – How to achieve this? • WLCG already has a level of trust both – via assertion • I trust this organization so I trust this site – years of effort 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Introduction • WLCG SOC working group • Two areas of work – Technology stack – Threat intelligence 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019

WLCG MISP • Initial plan – Start with sites pulling event data from WLCG instance – Via • web app (visually inspect data) • API client (direct to IDS) 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Current status • Currently have a handful of sites that have synced to WLCG instance • Most deployments in development phase • Following SOC Workshop in February focus on threat intelligence 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Call for participation • International participation • Started as WLCG group but widened scope – NRENs – Other academic institutions – EGI Fed. Cloud • Develop specific guidelines for WLCG, best practices for use in other communities 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
US involvement • Already have great participation from US – AGLT 2 – Very nice session at last workshop on deploying CERN scripts for SOC alert aggregation and correlation • Would love to see more sites involved – Great to have more experienced Zeek sites 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Considerations • GDPR – Very nice discussion by MISP – Incident Response under GDPR • Andrew Cormack 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Considerations • • Management Site admins Users CSIRTs 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
Conclusion • The technology to share intelligence already exists and is mature – In use in many communities already – We can benefit from this! • Need to work on the social and political process – Use the SOC WG as a forum for this 2019 Joint HSF/OSG/WLCG Workshop 19 March 2019
